Rangel’s opponents include state Sen. Adriano Espaillat, who would be the first Dominican-born member of Congress if he wins Tuesday’s primary and the general election in November, as well as Harlem minister the Rev. Michael Walrond Jr.

In endorsing Rangel, 84, Cuomo said his “experience, seniority, and steadfast commitment to improving the lives of New Yorkers continue to make him a critical voice in standing up to the Tea Party extremism that is threatening to take over Washington.”

Rangel has also gained endorsements from Sens. Charles Schumer and Kirsten Gillibrand, as well as former President Bill Clinton.

Espaillat has been endorsed by City Council Speaker Melissa Mark-Viverito and City Comptroller Scott Stringer. Campaign Manager Jesse Compoamor pointed to those endorsements and others in responding to the Cuomo announcement, saying, “Adriano Espaillat was 1,000 votes away from unseating Congressman Rangel in 2012 as an insurgent with no political support. Two years later, the call for change is even louder.”
